American Heritage® Dictionary of the English Language, Fourth Edition
- n. A black or blackish-red to brick-red mineral, essentially Fe2O3, the chief ore of iron.
Century Dictionary and Cyclopedia
- n. Native anhydrous iron sesquioxid, or redoxid of iron, Fe2O3. It crystallizes in the rhombohedral system, and occurs in iron-black crystals with brilliant metallic luster (called
specular iron and iron-glance), also in thin tabular crystals or scales, often red by transmitted light. More commonly it is massive, with structure varying from compact to foliated and micaceous (iron-mica or micaceous iron ore), also to columnar and fibrous, and further to earthy (red ocher) and impure argillaceous (ironstone) kinds”. All varieties have a red streak. It is one of the most valuable ores of iron, and is mined in large quantities, as in the Marquette region of Lake Superior. It is sometimes calledbloodstone and oligiste iron (fer oligiste); also often red hematite, to distinguish it from the related hydrated ore, brown hematite, or limonite, which has a brown streak. See cut underreniform . - n. An intaglio cut in hematite.

- n. (Min.) An important ore of iron, the sesquioxide, so called because of the red color of the powder. It occurs in splendent rhombohedral crystals, and in massive and earthy forms; -- the last called red ocher. Called also

Examples
“But the two things they have in common is they're landing in areas where we believe just based on the geological formations appear to have either been lake beds or could have sustained hematite, which is commonly found on earth-bound, you know, bottoms of lake beds, sediment and so forth.”
“Fully nine-tenths of the iron production of the world comes from the so-called hematite ores, meaning ores in which hematite is the dominant mineral, though most of them contain other iron minerals in smaller quantities.”
“The compass is useless on these hills, as they are composed of micaceous iron ore, with brown hematite, which is very magnetic.”
“France, called at the present day hematite, which is red in colour and is much employed for burnishing gold.”
“The key to determining if ultra violet light or oxygen formed the hematite is the crystalline structure of the hematite itself.”
“A soft, reddish mineral called hematite was mixed with the fat of an animal, such as a deer, to make a paintlike paste, Burge said.”
“Usually when an archaeologist reports "hematite," he is referring to the non-earthy forms.”
“The round rocks are actually found on Mars - called blueberries - hematite boles - formed by water running through sandstone.”

“Sundance Thursday announced it had more than doubled the most-reliable "indicated" measure of hematite iron ore in its Mbalam project to 417.7 million metric tons from a previous figure of 169 million tons, largely as a result of resources on the Congolese side of the border being moved from the less-reliable "inferred" category.”
“The metal has been identified since prehistory by its bloody signature of iron oxide, or rust; one of iron's principal ores, hematite, has had that bloody name since the 16th century.”
